VTiger beginner - where are these items?

Question

I am a beginner to Vtiger and I want to get a modification done. I need to understand the order of Vtiger functions.

So here are my questions:

1. What folder contains the bulk of the PHP functions? (Ex. vlib?), I searched all of the module files, these seem to call function included from somewhere else.

   To better define why I need to understand these locations, here is what I want to do: I need to modify the line items of a Product or Service in a Quote by adding a field. (I have already added the field to my MySQL table).

2. Where is the folder that contains the "update" function for Products and Services?
   Next I need the new information to appear on the quote output to PDF.

3. Where is the folder that contains the quote query function?

I seek answers that might help anyone who reads this speed up their learning curve of the Vtiger architecture, I do not expect anyone to do the work for me.

Answer 2

Not sure about all of your questions, i'm a vtiger newbie too, but vtlib library examples are located in /vtigerrootinstallation/vtlib/vtliblibraryversion, are you on windows or linux?

After little help from Wiki or the documentation, I did finally find a good answer here: Adding fields to Line Items

Here is the "list", its a great starter to learn the location of items

I've solved the issue!!! I can now insert fields into line items for quotes and sales orders and successfully store and retrieve them from the vtiger database. Here is a basic overview of what I did to add this functionality (which has been quite the learning process).

Alter the following table and add your new fields to it:

• vtiger_inventoryproductrel

The following files were modified:

• include\js\Inventory.js - Retrieves data from the DB
• include\utils\DetailViewUtils.php -Retrieves data from DB
• include\utils\EditViewUtils.php - Writes data to DB
• include\utils\InventoryUtils.php - Writes data to DB
• Smarty\templates\Inventory\ProductDetails.tpl -fromats new fields for display view
• Smarty\templates\Inventory\ProductDetailsEditView.tpl - formats new fields in edit view
• include\language\en_us.lang.php - Holds new labels for new fields

Again this is not a full solution but does provide location and direction
